"Our research shop, along with America Rising, has been focusing in on Hillary Clinton. But I agree with you that there needs to be a more of a focus," Priebus told Hewitt.

"I think that we have to be very aggressive on what she's done or hasn't done. And the things that she is famous for, like a botched healthcare rollout in the 90s, and Benghazi, and the things that she is involved with that are or went obviously pretty badly, we need to focus in on."

Priebus also revealed that the RNC is responsible for at least some of the "rough stuff" criticizing Clinton that makes its way into the media.

"I think that there's a lot of rough stuff coming out on Hillary that, you know, it doesn't just come out of thin air. It comes from somewhere. And sometimes, it comes from us, and sometimes, it comes from other groups," Priebus said.

Early polls overwhelmingly indicate that the former secretary of state is favored to win her party's nomination and is in the lead against all potential GOP presidential contenders.
